The utility model relates to construction equipment which is adopted during coarse adjustment of track panel construction of double-block ballastless tracks, in particular to a laser alignment type track gauge, and solves the problem that a center line during the coarse adjustment of double-block ballastless track construction is inaccurate. The laser alignment type track gauge comprises a digital display track gauge, wherein the digital display track gauge is arranged on track panels and is vertical to the longitudinal direction of the track panels, one end of the digital display track gauge is provide with a fixed end, the other end of the digital display track gauge is provided with a movable end, the fixed end and the movable end are respectively arranged at the inner sides of the track panels which are arranged at two sides in a clamping way, the digital display track gauge is fixedly provided with a rotating mechanism which can rotate around the digital display track gauge, and the rotating mechanism is fixedly provided with a cross-shaped laser transmitter which can be used for transmitting two lasers which are vertical to each other. According to the laser alignment type track gauge disclosed by the utility model, the coarse adjustment on the track panels is adopted, and the problems during existing track panel construction that the center line is unclearly and inaccurately scribed, plumb bob hanging is time-wasting and labor-wasting, the examination is not easy, and the like are solved.
